Work Health & Safety

The tragic death of a 60-year-old farm worker after falling from a hothouse roof is a reminder to all growers of the need for safe work systems. The worker had been attempting to remove plastic covering when he lost his balance and fell about 2.5 metres, suffering a fractured spine, spinal cord damage and quadriplegia. The worker passed away from health complications while in hospital following the incident. Safework NSW charged the business and its director with a breach of the Work Health and Safety Act 2011 (NSW) for failing to comply with their duty. They were both found guilty in the District Court and fined a total of A$165,000. Read More »

Do you need to whitewash a greenhouse with UV protective glass?

February 1, 2016
Rick Donnan

Your question implies that the main function of applying whitewash to a greenhouse cover is to prevent the transmission of UV (ultra violet) light into the greenhouse. This is not correct. The main function of whitewash is to reduce the heat load upon the crop in the greenhouse by reflecting a significant proportion of the incoming Infra Red (heat) portion of solar radiation. This is aimed at periods of high solar radiation, that is, around summer. Read More »

In the broad debate on climate change, the Australian horticulture industry is a small contributor of carbon dioxide emissions, representing just 1% of national agriculture emissions (National Greenhouse Gas Inventory 2007). However, while fertilisers are seen as the only source of emissions from horticulture in the national inventory, there are other direct and indirect emissions from horticulture, such as fuel and electricity. While net CO2 emissions are small, existing and future climate change policies place little importance on horticulture and particularly the protected cropping industry, which is a consumer of carbon dioxide to improve crop quality and yields.

Carbon dioxide options for commercial greenhouses

The changing landscape of fossil fuels presents increasing business risks for Australian domestic industrial and commercial energy consumers. Rising costs and uncertain supply of natural gas (1) and the existing high price of Liquid Petroleum Gas (LPG) represent a significant portion of this risk. Adding complexity to this changing landscape is mounting international pressure on Australian policy makers to replace fossil-fuelled energy with renewable alternatives. Horticulturists use natural gas and LPG for greenhouse environment management and as a result are left exposed to an uncertain future.
